> - If I want to join a new company, a technical blog or active developer advocates help me decide. I can get a sense of a company culture through what they chose to post and whom they hire for their advocate roles.

Working with some of these over the last forever.. I don't in any way believe they share anything about the company culture, or frankly the correct usage of the company's technology as it wants.

I very much see this as people who want to be fully-time developers, but aren't currently. Across orgs - I have yet to see this not be true, but maybe it's just me, and the others with whom I discuss this. Echo champers are very much a thing.
